Значення мелодії (серія Pixhawk)

Pixhawk-series flight controllers use audible tones/tunes from a buzzer and colours/sequences from a LED to indicate vehicle state and events (e.g. arming success and failure, low battery warnings).

INFO

Developers: Tunes are defined in /lib/tunes/tune_definition.desc and can be tested using the tune-control module. You can search for tune use using the string TUNE_ID_name(e.g. `TUNE_ID_PARACHUTE_RELEASE)
